MACHINE FOR MAKING COMES.

Application filed April 16, 1921.

To all 107mm it' may concern Be it known that we, GEORGE KonLMEYEn and CLAUDE E. lViNG, both residing at College Point, in the county ot Queens and State ot' New York, and HERMAN SCHEL- HAMMER, residing at lVhitestone Landing, in the county of Queens and State ot New York, all citizens of the United States, have jointly invented new and usetul improvements in Machines for lvlaking Combs, ot which the following is a description, such as will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to improvements in clamps for holding comb blanks in the operation ot' cutting or sawing away the web portions between the teeth, anl it is particularly adapted for use in connection with the machine shown and described in the patent granted to Frederick lV. Grell, machine for manufacturing combs, July G, 1897, No. 585,818.

A principal object of this invention is to provide a double or duplex clamp for holding two comb blanks in perfect registration so that the web portions between the teeth olf both blanks may be cut away simultaneously, thus greatly reducing cost of production.

A. further obj ect of this invention is to produce a double comb blank clamp of simple strong construction, easy to attach and dctach from the machine and comparatively inexpensive.

In the accompanying` drawings there illustrated different practical embodiments or the invention, but the constructions shown therein are to be understood as illustrative only, and not as defining the limits ot the invention.

Referring to the drawings:

Figure l is a general view ot a machine ttor making combs, and showing our impr ved double comb clamp secured in normal operative position.

Figure 2 is an enlarged plan view of the clamp.

Figure 3 is a front view; and

Figure -1 is a side view thereof.

Figure 5 is a plan view showing a modified construction.

Figure 6 is a iront view; and

Figure T is a side view thereof.

Figure S is a plan view showing a further modified construction.

Figure 9 is a front View; and

Figure l0 is a side view thereof.

a Figure ll is a plan view showing a still rurther modilied construction.

Figure l2 is a tront view; and

Figure 13 is a side view thereof.

For the purpose ot this description, it will only be necessary to describe the machine shown in Figure l in a general andfwe will proceed as follows:

In the drawings A designates the base ot the machine. ,B the carriage or support slidable on a track a formed lengthwise oft the machine. @n the upper part ot this carriage is supported our improved clamp C adapted to hold a pair et comb blanks D.

Journaled in bearings on the under side ot the carriage B is a screw E engaging a threaded cam F fixed to a shaft F .and this cam, in the operation of the machine, imparts to the carriage an intermittent step movement, as described in the above identilied patent. p

The saw or cutter is shown at H; and carried on a bracket J is a guide linger l engaging the successive web portions between the teeth ot the uppermost comb blank as the clamp is ted across the critter, and to maintain the uppermost blank against the finger l we provice a weight Vf suspended from the clamp.

Blocks 10 are mounted at the top ot carriage B at opposite sides oit the clamp C and are notched at ll to receive trunnions l2 projecting from 'the ends of the clamp C.

rl `he clamp as shown in Figures 2, and lw ay 5 comprises a yoke shaped iframe 1S constituted by a bar let having end heads or members 15 which are bored centrally to receive the trunnion pins l2. The heads l5 further provided with perforations lo to receive the trunnio-ns 1T, oi"- a pair ot' jaw members 1S having backward extensions i9 the extension of the upper jaw being oriiced and threaded to receive a winged clamping-screw 2O which extends through an opening in the bar let and bears against the extension 19 ot the lower jaw, as clearly shown in Figure t.

Positioned between the gripping part oi the jaws is a. clamp plate 2l arranged to lie between the comb blanks when clamped in position, said clampV plate being yieldingly held in position by lea't spring arms 22. By this construction combs oit' diliierent thickness can be clamped in position, that is, a thick one can be clamped with a thin one 'for Cutting.

Gauge wires 23 are ai'ichored on screws 2d and have angled extensions which range downwardly through openings 2G in the jaws 18 and clamp plate Q1 and which serve as stops for the backs oi' the. comb blanks to rest against, to determine the depth of the cut in the blanks.

1n the form ot' construction shown .1n Figures 5 to 7,` inclusive, the frame 13 is formed withV an integral clamp plate or tongue 27 held in `yielding relation with the clamp jaws 18 by` springs Q8 pulling in opj posite directions, the springs being secured at o-ne end to pins 29 on the `trame 13, and at the other end to armsBO secured to the upper and lower jaws. i

1n the form ot construction shown in Figures 8, 9 and 10 inclusive, we have shown a double coirb blank with tour aws 31 and four gauge lingers 82 extending` inwardly y through slots-l nearly to a clamp plate 34 yieldingly carriedon the trame 35 by leat' spring arms 36 and held centrally ot the jaws 31 by opposed springs 37` secured to the trame through pins 38 and to arms 39 on the opposite jaws 31.

Reterringto Figures 11, 12 and 13 of the drawings, we have shown a double clamp for holding line tooth combs which comprises a iframe 10 having a forwardly directed clamp plate l1 on which adjustable gauge plates l2 are secured by screws 113 passing through slots all. i

Clamp jaws 115 are hinged at 416 to the endsioi the frame and are clamped down `on the comb blanks by a winged screw 117 which passes loosely through the clamp plate 4:1. An end gauge i8 1s capable ol" adjustment on a screw 19 tapped in the upper aw L15.

The clamp plate a1 has guide` grooves 50 formed in the ends to receive, in sliding relation, the parallel arms oi a yoke :trame 51 adjustably carried on a. screw 52 swiveled in the frame et() and held against longitudinal movement by a cross pin 53.

The arms of the yoke 'trame 51 are formed each with a series of preferably tapered openings 5e adapted to receive pins (not shown) provided on the carriage of the comb making machine to hold the clamp `in operative position.

1t is thought that the operation and utility ot the device will be apparent without further description, and while in the drawings there is illustrated different practical embodiments oit the invention, it is to be nnderstood that the structural elements thereof are susceptible to such variations and modimeshes tications as tall within the scope of the appended claims.

What we'claim and desire to secure by Letters Patent, is:

1. A comb clamp comprising al trame', a pair of jaws, a clamp plate positioned between and spaced from the jaws, and a screw carried by one oi said aws and adapt.- ed to engage the other ot said jaws.
